To all whom 'it may come/rn:

Be it known that we, ARTHUR J. OTTo and CARL A. OTTO, citizens of theUnited States, residing at Milwaukee, in the county of Milwaukee andState of Wisconsin, have invented certain new and useful Improve-- mentsin Mounts for Thermostats, of which the following is a spepification.

This invention relates to thermostatic, hygrostatic, and similar controldevices intended to be mounted on a wall and provides a convenient andstable means for supporting the piping before connection to the eviceand before the wall is finished, and.

for supporting both the instrument andthe pipin in proper to the wallafter finishing o the latter,a

The invention permits the following procedure during the construction ofa building. A connection manifold known as a pipe head is mounted in arecess in the rough wall, which recess is made somewhat larger than isnecessary to receive the pipe head. 'lhe pipe head is permanentlyconnected by flexible metalhc tubing to the usual motive duid supply'pipe and to the pipe or pipes leading to the devices to be controlled.After the pipe head has been connected as described, it is temporarilyattached to a lng on ya mount plate and this mount plate is permanentlyfastened by nails, screws or the like to the-face of the unnished wallwhere it will later be concealed by the plaster. rllhe mount plate is anaperture through which the pipe head may be drawn and is preferablyformed with a boss below this aperture projecting nearly to the intendedsurface plane of the finished plaster., y V

Adjacent the aperture in the mount plate is the lug to which thefpipehead is teniporarily attached, 'and this lugis so positioned as to holdthe pipe head retract-cd into the recess in thel wall so that it isentirely out of the way during the plastering operation and unlikely,therefore, to be damaged, The plaster is brought to the margin of theaperture, and after the plastering has been finished, the pipe head isreleased from the mount plate and is drawn forward through the aperture.lt is then attached to a base plate which in turn is connected to theforwardly projecting boss of the mount plate by means of screws or theequivalent. ln this way the base plate seats on the finished wallsmoothly around the aperature without-I imposing close limits on thethickness of the plaster coat. The thermostat-is then clamped to thepipe head, making connection therewith in the usual manner, after whicha protecting cover is attached to 'the base plate.

- The preferred embodiment of the invention is illustrated in theaccompanying drawings, in which- Fig. is a vertical section on a planeperpendicular to the wall showin the thermostat and its' accessory partsall mounted 1n place;

Fig. 2 is a similar section showing the appearance of the parts beforeplastering when the mount plate lilas been connected to the ipe head andfixed in position on the wal Fig 3 is a face view of the mount platepgnnected with the pipe head as shown in nig.

3 Fig. l is a section on the line i-f of Fig. 5 is an elevation showingthe thermostat with its cover in place and indicating in dotted linesthe position of the mount plate;

Fig. 6 is a front elevation of the base platen 'lhe rough wall (orpartition) is indicated generally at 11 and a recess 12 is formedtherein to receive the ipe head 13. Such pipe heads rare known and haveported faces which mate with corresponding orted faces on the thermostatattached t ereto.

The pipe head 13 is connected by flexible metallic tubin 14; and 15 witha pressure Huid supply pipe and with a pipe leading to the device to becontrolled. rlhese pipes are not shown. rllhe controlled device might,for example, be a diaphragm motor connected to a radiate-1' valve in theroom. After the head 13 has been connected by the tubing lll and 15 asjust described, itis connected by means of a screw 16 with a lug 17formed on a mount plate 18. This plate is of generally rectangular forniand is provided on the marginal portions of its front facewitlrprojecting tongues 19 struck out forwardly from the plate andintended to key the plaster. The mount plate is also provided with aforwardly projecting boss 2() in which are the tapped holes 21 whichreceive screws to retain' the base hereafter lef opening throu h themount plate 18 and t is is surroun ed by a ange 22 which projectsforward from the mount plate and' terminates flush with boss 2d.

The parts are now in the condition shown in Fig. 2, so that the pipehead 1s thoroughly protected from injury during the plastering.. Thelaster 23 is applhed so that it is flush wi or rojects shg tly beyondthe front face of t e boss 20 and flange 22. Ween the plastering hasbeen completed and the thermostat is to be installed, the screwwithdrawn, and the pipe head i3 1s tilted to the rear to clear the lug17. The pipe head 13 is then drawn forward through the opening in themount plate, and connected with a base 2li preferabiycmolded oi somesuitable composition. This conne.- tion is made b three screwsntwo otwhlch pass through t e holes 33 (Fig: 6) and are threaded into the holes25 (see 1g. 3). The third screw is shown at 26 in Fig. 1..

rihe pipe head having been connected to the hase 211, the base is thenattached to the mount plate 18 by means of the screws 27 (see Fig. l)which pass through the hole 34 and slot 35 in the base 24 and engage thethreaded openings 21 in the mount plate 18. The slot allowsthe base tobe vertically aligned and when the base is fixed the pipe head is riidly held in proper relatlon the front face of the thereto. The termostatic'" device, indicatedy generally b the numeral 28, is nowconnected tothe pipe head 13 by means of screws, 'one of which is shownat 29 in Fig. 1. A cover 30 is `then mounted on the base 24 by means ofscrews 31 which are threaded into bushings 32 molded in the base.

It will be observed that the base is carried by the mount plate and that4the screws permit the base to be aligned and also to be fixed tightlyat its margin against the face of ,the plaster regardless of slighterrors in location of the mount plate and without imposing close limitson the thickness of the plaster over the mount plate. finished conditionthe pipe head carries the thermostat, and .is in turn carried by thebase, so that the relation of the thermostat to the base must becorrect.

The ease of mounting and the fact that the thickness of the plaster iscompensated for are important practical considerations.

What is claimed is:

1. In a mounting for control instruments, the combination of a movablepipe head; a mount adapted to be fixed in a wall, and having an aperturethrough which said pipe head may be moved; a base releasably suported onsaid mount; means for connectmg said pipe head to said mount at the rearthereof when said pipe head is retracted; and means for connecting saidpipe head to In the vsaid base and plate and between said base and pipehead.

3. Mounting means rior control devices which include a ported pipe headand a contro?L mechanism releasably connected therewith, comprising incombination, a mount plate arranged to be fixed in a wall and having anaperture through which said pipe head may he passed and means fortemporarily sustaining said pipe head to the rear oi said plate whiledisconnected from said control device; a base member; and means forconnecting said base member to the front of said mount plate and to saidpipe head when the latter is drawn through said aperture.

4. Mounting means for control devices which include a ported ipe headand a control mechanism releasaEly connected therewith, comprising incombination a mount plate arranged to be fixed in a wall beneath theplaster thereof and having a forward projection approximately thethickness of the plaster forming a boss and an adjacent aperture, saidplate carrying adjacent said aperture means for temporarily retaininsaid pipe head in a position tothe rear o said aperture; a baseoverlying said boss and aperture; and means for connectin said base tosaid boss and to said pipe head when drawn through said aperture.

`5. Mounting means for control devices which include a ported pipe headand a control mechanism releasably connected therewith, comprising incombination a mount plate arranged to be fixed in a wallbeneath theplaster thereof and having a forward projection approximately thethickness of the plaster forming a boss and an adjacent aperture; a baseoverl ing said boss and aperture; and means gor connectin said base tosaid boss and to said pipe hea when drawn through said aperture.

6. Mounting means for control devices of the type including a pipe headand a control mechanism releasably connected there,- to, comprising incombination a molded base; means for supportin said pipe head andcontrol device on sai base; a cover; means for attaching said-cover tosaid base; and adjustable means for fixing said base inalligned relationwith the surface of a w lll 7. Mountin means for control devices of thetype inclu -ng a pipe head and a control mechanism releasably connectedthereto, comprising in combination a molded base;

5 means for supportin said pipe head and control device on sai base; acover; means for attaching said cover to said base; and

adjustable means including threaded connections passing through openingsin the base at least one of which is elongated, to 10 retain the baseseated against the face of a Wall and permit adjustment angularly.
